not appearing, as the name of a city, in any ancient writer. But that this word 

 occurred, in such a sense, in the original text of Ptolemy, (Geograph. lib. v. c. 

 13.) and was afterwards converted by some ignorant transcriber into dahanissa 

 which still remains in all the printed and manuscript copies of that author will 

 he thinks, not be contested. The coin therefore was struck at Dardanossa, or 

 Daranissa, which seems to have been a town seated in Sophene, a province of 

 the Greater Armenia, in the reign of the emperor Commodus, where the Roman 

 power at that time prevailed,

FI. On the Double Horns of the Rhinoceros. By James Parsons, M. D., 



F. R. S. p. 32. 



When Dr. P. laid his natural history of the rhinoceros before the r. s. in 

 1 743, which is printed in number 470 of the Transactions, (Abridgment, vol. 

 viii. p. 692,) he had not an opportunity of showing a double horn to the mem 

 bers; he has therefore taken this occasion to present them with a sight of a 

 specimen of the horns of an African rhinoceros, brought from the Cape of 

 Good Hope, by William Maguire, Esq. What renders this subject the more 

 worthy of observation, is that, by means of knowing there is a species of this 

 animal, having always a double horn on the nose, in Africa, Martial's reading is 

 supported against the criticism of Bochart, who changed the true text of that 

 poet, in an epigram on the strength of this animal ; for when Domitian ordered 

 an exhibition of wild beasts, as was the custom of several emperors, the poet 

 says, the rhinoceros tossed up a heavy bear with his double horn : 



Namque gravem gemino cornu sic extulit urum. 

 and as Bochart knew nothing of a double horn, he changed this line both in 

 reading and sense, thus : 



•v Namque gravi geminum cornu sic extulit urum. 



as if two wild bulls were tossed up into the air, by the strong horn of the rhi- 

 noceros. 



The dimensions are as follow, viz. The length of the anterior horn, measuring 

 with a string along the convex fore part, is 20 inches; perpendicular height 18; 

 circumference 214^ at the base; the posterior horn is in perpendicular height 

 IQl; circumference round the base 18; length of both bases together on the 

 nasal bones 14; and the weight of both together is 14 pounds 10 ounces.
